| Abstract: | This paper introduced a design of intelligent photovoltaic solar LED street lighting system. According to the charge and discharge characteristics of lead-acid batteries, PWM charging mode was used to charge the batteries. To ensure that LED driver current is constant when the battery voltage drop or the ambient temperature rises, integrated circuit PAM2842 was used to control LED driver current. In addition, to ensure that the system is stable and reliable, the choice of solar panels and the design LED lamp was carefully selected. |
